Performance of Severely Hearing-Impaired Children on a Closed-Response, Auditory Speech Discrimination Test
The performance of 23 hearing-impaired children on a closed-response, auditory speech discrimination test and on an open-response, auditory speech discrimination test was compared to their performance on auditory tests of sensitivity, teacher-evaluated categories, and other related subject data. A comparison of the results of closed-response, auditory speech discrimination test and the open-response, auditory speech discrimination test indicates that the closed-response set test paradigm appears more productive for use with severely hearing-impaired subjects whose level of performance is low (but not 0%) on the open-response, auditory speech discrimination test. The closed-response test scores for this group are highly positively correlated to data dependent upon hearing function, whereas the open-response scores are not. Analyses of the closed-response set test results indicate that a closed-response set test paradigm can successfully demonstrate auditory speech discrimination error patterns on a subject group basis.
